Phil Mickelson will not defend his title at the PGA Championship this year amid fallout from his comments about Saudi Arabia and his links to the Saudi-funded rival golf league, the PGA of America announced Friday.

The organization was informed that Mickelson was withdrawing from the tournament even though the PGA welcomed his participation. Mickelson becomes just the third PGA champion not to defend his title in the last 75 years.
